QUESTION TIME: Around what week do mommies start going to the doctors more frequently (like once a week or once every 2 weeks or whatever it is)? I know I still have a pretty long ways to go for that but I was just curious; also if it turns out that you start to have some issues with your pregnancy (thank god I've been issue free for the most part and knock on wood I don't run into any issues) will they see you more frequently sooner than with a normal pregnancy? I don't know why these questions come to me out of nowhere so early on but I'm always the type of person that wants to be prepared for whatever and not taken aback because I wasn't aware of something that all I had to do was ask about.
